| Sumario: | [ANGLÈS] Optical Waveguide Light Spectroscopy (OWLS) is a type of label-free technique of optical bio-sensing. It is based on the coupling of laser light in an optical waveguide through a Diffraction Grating (DG) fabricated in the surface. The coupling angle is related with the instantaneous refractive index or thickness of a bio-layer growing over the DG. Thinking in multiple measurements simultaneously in this work, we present the design of electronic board and electronic control of a commercial array of 512 photo-detectors with a microcontroller. The array will be used for monitoring the output of multiple laser beams from the edge of an optical grating waveguide sensor. Data from the array are transferred using a USB cable to a Personal Computer for drawing and processing. |
